Hotshot Lead 2

Hotshot Lead 2 unlocks after completing Chain of Evidence with Tiffany, and Pendrew giving you the firearms tutorial.

Consider doing other side missions (Fight Club, Racing, etc.) to increase your Face level to use better clothes (and better bonuses) before advancing, since you want to increase the Cop XP earned from these missions.

Get into the van and go to Hotshot's last location and plant a bug under his car before time runs out (90 seconds). Return to the van and shadow Hotshot to his different destinations. Call Teng and drive back to the Undercover HQ in Northpoint. If you completed Payback, you go to bed to pass the time.
